Chapter 20.7, Problem 1.2ACP

Interpretation Introduction

Interpretation:

The equilibrium constant $\text{K}$ for the reaction has to be determined.

Concept introduction:

• If the oxidation number of an element increases then the element is said to be oxidized and the oxidation number value of decreases for an element which is reduced.
• $E_{cell}^0=E_{cathode}^0-E_{anode}^0$
• In cathode, reduction reaction will take place and in an anode oxidation reaction will happen.
• The equation to determine the equilibrium constant $K$ by using the value of $E^0$ is,           

  $\ln K=\frac{n{E}^0}{0.0257}$     n is the number of electrons involved in the reaction
